thắc mắc Sử dụng DHTMLx để làm biểu đồ gantt

gantt.init("gantt_here");

gantt.parse({
    data: [
        { id: 1, text: "Project #2", start_date: "01-04-2023", duration: 18, progress: 0.4, open: true },
        { id: 2, text: "Task #1", start_date: "02-04-2023", duration: 8, progress: 0.6, parent: 1 },
        { id: 3, text: "Task #2", start_date: "11-04-2023", duration: 8, progress: 0.6, parent: 1 }
    ],
    links: [
        {id: 1, source: 1, target: 2, type: "1"},
        {id: 2, source: 2, target: 3, type: "0"}
    ]
});
